Learn how to untrack a committed file in Git and restore it from the repository using --source=HEAD! 🚀

In this hands-on tutorial, you’ll understand what happens when you use git rm --cached, why git restore fails for untracked files, and how to correctly restore files back into the staging area.

This is a must-know concept for mastering Git file states and avoiding common mistakes.

🎯 What You’ll Learn

👉 How to untrack a file using git rm --cached
👉 Difference between tracked and untracked files
👉 Why git restore fails for untracked files
👉 How to restore files from repository using source HEAD
👉 Understanding git status -s output (D and ?? states)
👉 How staging, working directory, and repository interact

🧪 Hands-On Lab Covered

Creating a file in working directory
Staging and committing a file
Validating repository using:
git show --name-only
git log --name-only
git show HEAD:file1.txt
Removing file from staging using git rm --cached
Understanding D and ?? states
Verifying staging using git ls-files
Restoring file into staging from repository
Validating working directory and staging

💡 Critical Concept (Very Important)

👉 After git rm --cached:

File is removed from staging
File becomes untracked
File still exists in working directory
Repository still has the file

👉 That’s why normal restore fails:

git restore file1.txt ❌ (fails)

👉 Because Git cannot find the file in staging

🔥 Correct Way to Restore

Use:
git restore --source=HEAD --staged file1.txt

👉 source HEAD → fetch from repository
👉 staged → restore into staging area

🔑 Key Insight

👉 Untracking does NOT delete the file from disk
👉 git rm --cached removes file from index (staging)
👉 Repository still keeps the file safe
👉 You can always restore from HEAD

⚡ Key Takeaway

👉 If a file is untracked, Git restore will fail by default
👉 You must explicitly specify the source (HEAD) to restore it

🔑 Commands Used

git status -s
git ls-files
git add file1.txt
git commit -m "Adding file1"
git rm --cached file1.txt
git restore --source=HEAD --staged file1.txt
git show --name-only
git log --name-only
